TL;DR South Korea has passed legislation that would cause breaking TOS agreements in software to carry 5 years of jailtime. This is apparently a result to PC Bangs (Korean cyber cafes) hosting tons of hackers. Walk in, load KILLALLNERDS.EXE on your terminal, pwn faces in Overwatch, get banned, leave, cafe generates new license, come back an hour later, repeat. But I can't help but wonder... wouldn't like, preventing user input or advanced UAC rules prevent the cost for lobbying for such a ridiculous law?

Obviously the law is absurd on its own, has implications that reach far beyond the intent, and sets a hugely dangerous precedent. Especially if you think about the now over-proliferation of the recently legitimized (in the US, anyway) non-arbitration clause so common in every TOS in the last 4 years.

Keep in mind that South Korea is also the country that has passed some utterly draconian shit already under the guise of "Controlling addiction". This is not a stretch.

https://en.wikipedia.org/wiki/Video_gaming_in_South_Korea#Video_game_addiction wrote:Video game addictionDue to problems of widespread video game addiction threatening the health safety of players and after different incidents related to it,[26] the Korean government has spent millions of dollars on clinics, campaigns, and programs to minimize the problem.[22] By late 2011, the government took a step further and imposed the “Cinderella Law”, also known as the Shutdown law,[22] which prevents anyone aged under 16 from playing games online between 10 pm - 6 am.[27] "Minors are required to register their national identification cards online so that they can be monitored and regulated".[22]

(Emphasis mine)

So expect it to pass.

But expect it to be a fight when it actually comes to court. And expect the US to watch carefully.

Even if South Koreans roll over for it, they have a very different legal and regulatory environment than the rest of the world. Lots of South Korean laws overreach like crazy and the legal system is stupidly stringent at times, especially related to the internet.

A lot of this stuff only works in SK, because registering for a lot of things on the internet there require you provide the SK equivalent of your SIN and all online accounts hosted in Korea must be traceable to a real person by law. Which also makes it fairly difficult for non-Koreans to obtain game mods or similar things created and hosted on only Korean sites.

That doesn't fly in a lot of other places. For instance, in Japan, the opposite is true and it's actually illegal in almost all circumstances for corporations to ask for your SIN-equivalent (which contributes to Japan's problem with self-disappearing people since you can get by in the sub-economy with a made-up identity in a way which would be much harder than even, say, the US).
